Interesting technology. It wouldn't hurt to try the vest as an insulation layer if the price is reasonable. My guess is that the technology will have very little effect on earth. In space where heat transfer is slow the minute extra bit of heat retention would probably be helpful but I have a hunch it wouldn't make that much difference in the atmosphere.
I would stay away from the jackets until you find out how breathable they are. This is the big issue with cycling. Most things that are waterproof are not breathable enough.
